“Hurricane season brings a humbling reminder that, despite our technologies, most of nature remains unpredictable”*…
Still, as Katarina Zimmer explains, an emerging science can help us improve our forecasts…
… contemporary simulations suggest the Great Colonial Hurricane was a Category 3.5 storm, probably the strongest in recorded eastern New England history. (For reference, Sandy, which killed nearly 150 people and caused some $65 billion in damage in the United States, was technically no longer even a hurricane when it made landfall in the New York metro area in 2012.)
Scientists know about the Great Colonial Hurricane’s impact not only from written reports but curiously, also from hidden, physical impressions the long-ago storm left on the landscape.
At the bottom of a pond, Jeffrey Donnelly, a hurricane scientist at the Woods Hole Oceanographic Institution, and his colleagues found subtle, buried evidence of the storm that almost felled the Mather line. The researchers were collecting sediment cores from a lakebed on Cape Cod. The spot, known as Salt Pond, lies about a third of a mile from the ocean and has long been a place of mud. But in their core samples, they found a pinky finger-thick layer of pure ocean sand in layers that dated back to roughly 1635. The only thing that could have pulled that much beach material over the sand barrier and that far inland was a truly massive storm.
The cores revealed other clues, too. Although written accounts suggest the 1635 tempest was the strongest of its time, the exhumed samples showed it wasn’t the only intense storm in the area. Donnelly found evidence for 10 major storms in the area between 1400 and 1675—a surprising toll, given that major hurricanes are virtually unheard of this far north today. The fact that hurricanes were much more frequent in the past begs the question of why, and whether these levels of storm activity could someday return.
Which is why researchers like Donnelly are traipsing along coastlines and digging in the muck. They hope their relatively new branch of science, paleotempestology (the study of old storms), can use these buried traces of long-gone winds to augur ancient patterns. Patterns that might also help us predict the weather that lies ahead…
Paleotempestology promises to uncover patterns of historical hurricanes—to better predict destructive weather of the future. More at: “The Secret Messages in Ancient Storms,” (or here) from @katarinazimmer in @NautilusMag.

As we muse on the meteorological, we might send exploratory birthday greetings to Bernard Brunhes; he was born on this date in 1867. A geophysicist, he is known for his pioneering work in paleomagnetism, in particular, his 1906 discovery of geomagnetic reversal [see here]. The current period of normal polarity, Brunhes Chron, and the Brunhes–Matuyama reversal are named for him.
Brunes made his discovery in a way that presaged the work of paleotempestologists: he found volcanic lava and clay samples that recorded the Earth’s inversion of its magnetic field.
“Ice contains no future, just the past, sealed away”*…
From her new book, Ice: From Mixed Drinks to Skating Rinks—A cool history of a hot commodity, Amy Brady…
Despite more than 150 years’ worth of study and experimentation, no one really knows why ice is slippery….
Nineteenth-century Americans used ice to store perishable foods in amounts that astounded visitors from Europe, where an ice trade had yet to be developed. Apples, for example, became so commonplace in the young republic that visitors coined the phrase “as American as apple pie.”…
By WWII, the burgeoning industry of electric refrigeration was catching up to the ice industry, and companies like the Southland Ice Company were forced to rethink their business plans. Southland began selling kitchen staples like milk and bread alongside their ice. The combination became so popular, the company extended its hours to keep up with demand, and within a few years renamed itself after its new hours of operation. The 7-Eleven was born, and convenience stores today still sell ice…
Between WWII and 1975, the amount of electricity refrigerators consumed grew by more than 350 percent. Today, a look at energy use around the globe reveals that the cooling industry (refrigerators, freezers, and air conditioners) accounts for almost 10 percent of all CO2 emissions…

As we chill, we might recall that it was on this date in 1982 that record low temperature of -117 F was recorded in Antarctica. That record was broken the following year, also in Antarctica, at -128.6 F– a mark that stands to this date, as Antartica has been warming… leading Dr. Brady to ask, “in an age of accelerating global warming… can ice in the freezer and ice on our planetary poles continue to coexist?”

“I don’t believe in astrology; I’m a Sagittarius and we’re skeptical.”*…
(Roughly) Daily has looked at almanacs before (e.g., here and here), but never with an eye to their astrological underpinnings. Livia Gershon plugs that gap…
Some Christians today see astrology as a clear affront to their beliefs, and possibly a dangerous manifestation of the occult. And yet, as historian T.J. Tomlin writes, through the eighteenth century, it was a central aspect of the almanacs that were ubiquitous in Protestant American homes.
By 1800, Tomlin writes, U.S. printers produced enough almanacs to provide one to every household in the country. People turned to the books for a clear, simple idea of how the universe worked. Their astrological calculations helped readers gain practical know-how about agricultural management, weather, and personal health.
…
Like the study of the natural world in general in that time and place, almanacs were rooted in Protestantism. They presented simple, widely held religious ideas—God’s power, redemption through Christ, the promise of heaven—to an increasingly literate public. “This was the liturgy of early American popular culture,” Tomlin writes.
But there were debates about what sort of astrology was compatible with this religious belief. “Natural astrology,” using the movements of heavenly bodies to draw conclusions about agriculture, medicine, and the weather, was widely regarded as “a way to illuminate God’s creative impulse in the universe,” Tomlin writes. But “judicial astrology,” predicting the events of individual lives or political affairs, might be seen as blasphemous…

As we study the stars, we might send multi-faceted birthday greetings to the painter, sculptor, architect, musician, mathematician, engineer, inventor, physicist, chemist, anatomist, botanist, geologist, cartographer, and writer– the archetypical Renaissance Man– Leonardo da Vinci. Quite possibly the greatest genius of the last Millennium, he was born on this date in 1452.
While Leonardo’s attention (and thus his notebooks) extended to astronomy, there’s no evidence that he believed in astrology. That said, his chart has been cast myriad times (e.g., here).

“The sea hath fish for every man”*…
A few weeks ago, (Roughly) Daily shared the story of The Illinois Department of Natural Resources’ attempt to rebrand invasive Asian Carp as Copi in an attempt to make it a more appealing food. Kane Hsieh, writing in Spencer Wright‘s always-illuminating The Prepared, elaborates on the theme…
… It’s worked in the past: Chilean sea bass (Patagonian toothfish), monkfish (goosefish), and uni (urchin, also called whore’s eggs by American fisherman as recently as 1990) were all successful rebrandings.
Speaking of fish, it’s always a surprise to me how much of what feels like traditional cuisine is actually very modern, accidental, or even engineered. In Japanese cuisine, tuna and salmon rose to their contemporary status only in the 20th century: tuna was a poor man’s fish until post-war Western influence brought a taste for fattier meat, and salmon was an undesirable fish until the 80s when a desperate Norwegian government ran aggressive ad campaigns in Japan…

As we contemplate cuisine, we might recall that it was on this date in 1838 that it rained frogs in London. Indeed, there have been numerous instances on polliwog precipitation in the area, most recently in 1998, when an early morning rain shower in Croydon (South London) was accompanied by hundreds of dead frogs.
